PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 557,559, dated April '7, 1896.

Application filed June 29, 1892. Renewed November 22, 1896. Serial No. 569,836. (No model.)

To aZZ whom it may concern:

Be it known that I, THORWALD CHR. DAM- BORG, of the city and county of Philadelphia, and State of Pennsylvania, have invented an 5 Improvement in Printing-Presses, of which the following is a specification.

My invention relates to printing-presses; and it consists of certain improvements which are fully set forth in the following specification and are shown in the accompanying drawings, which form a part thereof.

The object of my invention is to accomplish the printing of cards, envelops, &c., with great rapidity and precision. In printing presses designed for this purpose, in which the articles to be printed are fed between rotary cylinders, more or less difficulty has been met in evenly supplying and spreading the ink upon the type-plate of the rotary type-cyl- 2o inder.

In carrying out my invention I employ devices for evenly distributing the ink upon the type of the cylinder by means of a rocking ink-distributing roller moving successively 25 in contact with inking-rollers. By means of suitable power-transmitting devices the inking-rollers operate at a comparatively slow speed, while the type and impression cylinders may rotate with great rapidity.

My invention also relates to certain novelties in the construction, arrangement, and combination of the inking-rollers and of the devices for operating them and of the rotary type and impression cylinders.

My invention also relates to certain other novel combinations and arrangements of parts, which are hereinafter more fully described and claimed.

In the drawings, Figure 1 is a side elevation of a portion of my improved printing machine, showing the type and impression cylinders, the inking-cylinders, and their connections. Fig. 2 is a similar view to Fig. 1, looking at the opposite side of the machine. Fig. 8 is a front elevation of the machine on a slightly-reduced scale from that of Figs. 1 and 2, with the lower front portion of the machine in vertical section. Fig. 4 isa vertical sectional View through a portion of the power- 50 transmitting gearing of Fig. 3. Fig. 5 is a side elevation of the lower portion of the machine upon a scale corresponding with Fig. 3. Fig. 6 is a vertical sectional view on the line 00 m of Fig. 3. Fig. 7 is a detail transverse vertical sectional view of the ink-fountain and its rollers. Fig. 8 is a longitudinal sectional view of a portion of the impressioncylinder. Fig. 9 is an enlarged detail plan view of a portion of the mechanism for imparting motion to the inking-rollers. Fig. 10 is a similar view, with part in section, of aportion of the power-transmitting devices for rocking the ink-supplying roller. Fig. 11 is a vertical sectional view, on an enlarged scale, on the line 5.2 of Fig. 3; and Fig. 12 is a similar vertical sectional View on the line 20 w of Fig. 3.

WVhile certain improvements in the devices for feedingand centering the cards, envelops, or other objects to be printed between the type-cylinder and impression-surfaces and also certain improvements in the means forsecuring the type-plate to the impression-cylinder are shown and described hereinafter,these particular improvements are not claimed in the present application, but form the subjectmatter of divisions herefrom. The feeding and centering devices form the subject-matter of the divisional application, Serial No. 506,982, filed April 4, 1894, and the improvements in the type-cylinder form the subjectmatter of the divisional application Serial No. 506,983, filed April at, 1894.

A is the frame of the machine.

B is a feeding-table.

C is the type-cylinder, and D is the impression-cylinder.

E F F and E F F are inking-rollers for inking the type.

G is a rocking ink-supplyin g roller for supplying ink to the rollersE and E.

II is a feeding-roller for feeding ink to the rocking roller G from the ink-trough I.

J J are upright frames on the sides of the machine, which carry the inking-rollers and typecy1in der.

K is the driving-pulley upon the shaft k. By this shaft is is carried the type-cylinder O.

L L are standards carried by the frames J J, in which are journaled the inking-cylinders F F and F F adjacent to the type-cylinders to supply ink to the type-plate thereof. The

rollers E and E are journaled in bearings e and e in the standards L L adjacent to the rollers F F and F F, respectively, with their surfaces in contact therewith. The bearings f f f f and e e are preferably open or cupshaped, as shown, so that the rollers E F F and E F F may be removed therefrom when desired.

K is a gear-wheel carried by the shaft is gearing with a wheel K which is carried upon a sleeve 7t loose upon the rock-shaft M. (See Fig. 4:.)

m is a pinion upon the sleeve gearing with the wheel K fast upon the sleeve 'n on a stud N. The sleeve '17. carries a pinion m, which gears with the wheel K upon the shaft h of the fountain-roller H.

E E are gear-wheels upon the shafts of the rollers E E gearing with the wheel K The rock-shaft M is journaled in the frames J J and carries standards M M, in which the shaft 9 of the rocking roller G is journaled. (See Fig. 3.)

M is a crank carried by the rock-shaft M and connected by the pitman O with the pin 1) of the rotary disk 0, which is carried upon a stud ofrom an arm A of the frames J. (See Figs. 1 and 10.)

The disk 0 is provided upon an inner annular flange 0 witha series of notches p,which are adapted to receive the end of a pawl 0 This pawl O is pivoted upon the disk P, carried loose upon the stud 0, immediately adjacent to the flange 0 of the disk 0. A spring 0 presses the end of the pawl upon the inner notched face of the flange 0 so that it will engage with the notches 13 therein.

0 is a connecting-rod having one end connected with the wrist-pin 19 upon the disk P and the other end connected with a wrist-pin 19 upon a disk P (See Figs. 9 and 10.) The disk P is carried by the shaft h and rotates therewith. The rotation of this disk P through the con necting-rod O rocks the disk I and with it the pawl 0 which successively engages with the notches p in the flange of the disk 0 and imparts an intermittent rotation to it. This rotation of the disk 0 intermittently reciprocates the pitman O, which in turn rocks the shaft M and moves the roller G intermittently in contact with the rollers E and E. By means of these power-transmitting connections the roller G is rocked at a low rate of speed while the printing-cylinders are operating at a high speed.

P is a friction-band about the disk 0 to prevent backward movement thereof.

E from the gear-wheel K It is desirable to impart a slight longitudinal movement also to the rollers E E, and I will now describe the devices employed for that purpose, referring more particularly to Figs. 1, 3, and 9.

Q, is a bevel-gear carried by the shaft hand drives the bevel-gear Q, journaled in the sleeve Q upon the frame J.

Q is a disk carried by the bevel-gear Q and provided with a pin (1.

Q is a rod having a slot g which receives the pin (1 of the disk Q Q is a horizontal lever pivoted at its middle to the frame of the machine and having its ends provided with pins or projections 1 which project between disks or arms e c upon the shafts of the rollers E and E, respectively. The rod Q is connected with the horizontal lever Q and rocks the same upon its pivot by the rocking motion received from the rotating disk Q The movement of the horizontal lever Q will produce a slight longitudinal movement in the rollers E E. To permit this longitudinal movement without breaking the gearing connection between the gears E and E respectively, with the gear K the teeth of the latter are made of greater breadth than the teeth of either of the gears E E The trough I may be adjusted by the screws 11 to or from the surface of the ink-feeding roller H to allow the ink to. flow more or less freely therefrom in the usual manner.

I will now describe the devices for insuring the proper feeding and centering of the card or envelop between the cylinders C and D, referring more particularly to Figs. 1, 2, 3, 6, 11, and 12.

A is a rock-shaft journaled in the main frame A at the end of the feeding-table B immediately in front of the type-cylinder C.

A is a rod or bar immediately above the rock-shaft A and carried thereby. Ct are springs connected with the rod A to normally hold it and the rock-shaft in a given position.

R B, Fig. 3, are stop-fingers carried adj ustably upon the rock-shaft A and projecting down into the path of the card or envelop and passing between the cylinders. I prefer to form the cylinder D with grooves (Z, into which the ends of these fingers project, so as to effectually prevent the passage of the card or envelop to the cylinders under the fingers R R, except when they are raised. I employ a series of these grooves to receive the fingers R R in their several positions of adjustment to suit different sizes of cards, the. R is a projection carried by the rock-shaft 1A-, and D is a cam upon the shaft of the cylinder D, adapted to strike the projection R and rock the shaft A so as to lift the fingers R R and permit the card or envelop to pass under them and between the cylinders O and D.

r r are nipping-fingers carried by the cylinder D and adapted, when the card or envelop passes under the raised fingers R R, to seize and hold the end of it While it passes under the type-plate.

In describing the construction of the cylinders D and E, I will refer more particularly to Figs. 6, 8, 11, and 12.

D is the impression-surface carried by the cylinder D, having one end held by a clamp d in a recess 61 and the other end turned about a roller D j ournaled longitudinally in the cylinder. The roller D may be rotated to unroll ortighten the impression-surface.

D is a ratchet on the end of the roller D and d is a pawl engaging therewith to hold the roller against movement.

R is a rock-shaft journaled in the cylinder D below the surface thereof and adjacent to the end of the impression-surface D The nippers or fingers r r are carried by this rock-shaft R and are adapted,when the rockshaft is turned, to be snapped over upon the impression-surface D to hold the card or envelop thereon. A spring 4", connected with the rock-shaft R normally holds the fingers back. (See Fig. 11.)

R is a projection upon the end of the rockshaft R adapted to strike an arm 1) upon the frame A to turn the rock-shaft R and snap the fingers 1" over, as has been heretofore described.

R is a second projection carried by the shaft R whichis adapted to be operated by a cam D The arm I) through the projection R turns the shaft R and snaps the nippers upon the card or envelop, and the cam D operating upon the projection It, holds the shaft against movement and keeps the nippers upon the card or envelop until it has passed between the cylinders D and 0, when the shaft is turned by the spring 1* and the nippers are moved back to their former positions.

O is the type-plate, which maybe attached to the type cylinder 0 in any convenient manner.

The shaft (1 of the cylinder D is j ournaled in an arm S of the bell-crank lever S, which is pivoted to the frame A at s and extends down to the base thereof. (See Fig. 5.)

WV is a cam adapted to bear against the end of the bell-crank lever S to normally hold the arm S thereof raised with thecylinder D in operative position with reference to the type-cylinder C.

V 7 are treadles for operating the cam WV to move the bell-crank lever S and raise and lower the cylinder D. The end of the bell-crank lever S may be provided with an adjustable-screw w to adjust the position of the bell-crank with reference to the cam. By this means the cylinder D may be thrown out of operative position whenever it is desired to stop the operation of the machine and may be raised into operative position again by operating the cam W through the foot-treadle W It is apparent that the bell-crank lever may be moved by hand, if desired.

S is a portion of the lower main frame A Within which the cylinder D may move. The shaft d of the cylinder D is driven by the shaft through the gears K and K T is a chute or guide for the printed cards or envelops, in which they are received when delivered from the cylinders C and D.

V is a reciprocating plunger for pressing the cards or envelops down the chute T.

V is a bell-crank carrying the plunger V and operated through the pitman U from a crank U of the shaft is.

G G are brackets upon the frame of the machine to support the inking-rollers when they are removed from the bearings.

Having described the mechanical construction of the machine, the arrangement of the parts, and their relation one to another, I will now describe the operation of the press in printing.

Power is imparted to the shaft 70, and the cylinders C and D rotate together through the gearing K and K Ink is supplied to the type-plate of the cylinder 0 by the rollers F F and F F, which receive ink from the rollers E and E, respectively. These rollers E and E are rotated through the gearing K E and E and at the same time receive a slight longitudinal movement by the rocking of the lever Q, as has been heretofore described. The shaft h is also rotated and supplies ink from the trough I to the roller G, which rocks intermittently from side to side, receiving ink from the roller H and successively touching the rollers E and E. The rocking movement of the roller G is comparatively slow, while the cylinders D, C, E, and E may be rotating at a high speed. The roller G replenishes the supply of ink upon the rollers E and E as the ink is used in inking the type. The articles to be printed are fed one at a time from the table B to the fingers R, by which they are stopped and prevented from passing between the cylinders until the cam D strikes the projection R and rocks the shaft A so as to lift the fingers R and permit the card to pass under the cylinders. The arm R of the rock-shaft R strikes the projection or finger Z), and the nippers 0" are snapped over upon the card, and the cam D acting upon the arm R as the cylinder D rotates, holds the nippers upon the card until it has been carried between the cylinders O and D and has received the impression from the typeplate 0. After passing the cam D the arm R is released and the rock-shaft R is turned back by the action of the spring 4", moving the nippers back into position to be snapped on the next card in the manner just described.

The stop-fingers B may be adjusted longitudinally upon the rock-shaft A to suit the size of the card, envelop, or other object.

The inking of the roller G may be stopped, when desired, without interrupting the operation of the cylinders C and D, as has been heretofore stated, by disconnecting the rod 0 from the disk P. hen the feeding of cards or envelops is interrupted temporarily or otherwise and it is not desirable to stop the entire machine,the cylinder D may be dropped away from the type-cylinder C by operating the bell-crank lever S through the foot-treadle IV, and it may be again raised into operative position by depressing the treadle W IVhile it is preferable to employ two sets of rollers E F F and E F F, one of these sets may be omitted, if desired, these and other minor details being capable of variation without in any way departing from the invention.

What I claim as new, and desire to secure by Letters Patent, is

1. In a printing-press, the combination with the fountain-roller, and ink-distributin g roller, of an intermediate rocking inksupplying roller, a pawl-and-ratchet device, driving connections between the pawl-and-ratchet device and an operative portion of the press, and connections between the pawl -and -ratchet device and the rocking supplying-roller, the ratchet-teeth of the pawl-and-ratchet device being disposed at such a distance apart as to impart to the roekin g ink-supplying roller upon each operation a movement through an are between the peripheries of the fountainroller and distributing-roller, whereby, upon each operation of the ratchet, the supplyingroller is moved from contact with the fountain-roller into contact with the distributingroller or vice versa.

2. In a printingpress, the combination with the distributing-rollers E, E, and the medially-located fountain-roller, of the rock ing ink-supplying roller located between the distributing-rollers E, E, a ratchet provided with four equidistant teeth, a pawl for operating the ratchet, and connections between the ratchet and the rocking ink-distributing roller, whereby, upon each movement of the ratchet, the rocking supplying-roller will be moved from contact with the fountain-roller into contact with one of the distributing-rollers or vice versa.

In a printing-press, the combination with the type'cylinder, the two distributing rollers E, E separated a distance apart, the

fountain-roller above the distributing-rollers, and the rocking supplying-roller located between the two distributing-rollers E, E, and movable on an axis below the fountain-roller in an arc tangential to the periphery thereof, whereby the rocking roller shall intermittently touch the fountain-roller and the two distributing-rollers.
